Inventor: NISHINOMIYA NOBUYUKI
IPC: B01J3/00
Filed: 1983-08-08
Abstract: PURPOSE:To obtain the clean high vacuum by a method wherein a hydrogen occluding material is placed at the side of a back pressure of a turbo particle pump, the hydrogen at the back pressure side is absorbed by the hydrogen occluding material to reduce the partial hydrogen pressure at the back pressure side and the arriving degree of vacuum of the turbo particle pump is increased. CONSTITUTION:The discharging port of the turbo particle pump 1 is extended by a flexible tube 2 to connect the port to a cartridge 3 filled with the hydrogen occluding alloy such as ZrVFe, TiZrFe2 or the like and the cartridge is connected to the suction side of an auxiliary pump such as an oil rotating pump 4, for example. The tightly enclosed space 5 of a vessel or the like to be evacuated is connected to the suction side 1a of the turbo particle pump 1. According to this method, the hydrogen in the back pressure side is absorbed into the hydrogen occluding material to reduce the partial hydrogen pressure at the back pressure side and the arriving degree of vacuum of the turbo particle pump 1 may be increased. Accordingly, the clean high vacuum may be obtained and an arrival time to the vacuum may be shortened.

Title: Camera and photographic printing method
Inventor: SAKAMOTO KIICHIRO
IPC: G03C5/08
Filed: 1989-06-07
Abstract: PURPOSE:To finish a photographic film to the true colors of a subject by providing a means for manual inputting of weather information and means for recording which records the inputted weather information to a part of the photographic film. CONSTITUTION:A knob 22 is operated according to the weather state at the time of photographing to match a pointer 22a with any of weather marks at the time of photographing. An aperture plate 20 moves cooperatively with the operation of the knob 22 to control the quantity of the incident light on a photographic lens 10 when this knob is operated. A brush 30 slides on a contact plate 31 simultaneously therewith and generates a code signal to indicate the kind of the weather mark. This code signal is converted to bar codes by a bar code converter 32 and is sent to a driver 35. The driver 35 operates to drive a bar code recorder 36 in synchronization with the operation of a shutter mechanism 12. A flash discharge tube 38 emits light during the liquid crystal display 37 displays the bar code and imprints the bar codes indicating the weather information in the peripheral part of an image plane 18a. The finishing of the photographic film to the colors faithful to the subject is executed in this way.

Abstract: PROBLEM TO BE SOLVED: To achieve the compatibility of the acceleration of high-density recording by the improvement of resistance for burst errors and the reproduction of the recording by high accessibility and a higher data-transfer rate. SOLUTION: Under the conditions, wherein the number of rotations is constant and recording and reproduction are performed at the variable data-transfer rate so that the recording linear density becomes constant between zones, the data blocks obtained by dividing one sector into two parts undergo the recording and reproduction at the isochrony from the respective segments at the innermost surface and the outermost surface of the disc in such a way the sectors are [DB1, DB2] → [DB3, DB4]... by two optical heads. Thereafter, the tracks at the respective outer surface side and the inner surface side are sequentially accessed, and the recording and the reproduction are performed so that the sectors are [DB5, DB6]...[DB7, DB8].... Here, the sector is the fixed-length data unit, to which an error correcting code is attached.  Furthermore, the data, which have isochrony and are recorded and reproduced by two optical heads, are in correspondence with the segment having the position relationship so that the amount of total data per constant rotating angle of the disc becomes equal all the time.

Abstract: PURPOSE:To eliminate the need for the core gap of an autotransformer and then miniaturize it. CONSTITUTION:Taps u2 and u3 are provided at the winding of an autotransformer Tr1 without any gap at a core, the circuit of switchers CB4 and CB3 are provided between a terminal u1 and an electric motor M and between the tap u2 and the electric motor M, and the circuits of current-limiting reactor Lx and a switch CB2 are provided between the tap u3 and the electric motor M. A terminal n is connected to the switcher CB1 for neutral point. First, the electric motor M is started with a low voltage when the CB1 and CB2 are turned on. Then, the CB3 is turned on, the CB1 is turned off, and then the electric motor is started with the winding between u1 and u2 as a reactor. At this time, the winding between u1 and u2 becomes a primary side and a secondary voltage is generated at the other winding part. Since the reactor Lx short- circuits u2-u3 so that the impedance of the winding between u1 and u2 is reduced and functions as a short-circuiting impedance. Therefore, the core iron is not saturated even without any gap for reducing size. Finally, CBu is turned on to achieve a total voltage operation.

Title: Interpolating device for error correction
Inventor: SENOO TAKANORI
IPC: G11B20/18
Filed: 1985-07-02
Abstract: PURPOSE:To prevent the mixed regeneration of data obtained before and after the interruption of data by interleaving when the data interruption is occured by generating a flag indicating a data error during the period up to the completion of interleaving. CONSTITUTION:Data read out from a recording medium are written in a data memory circuit 1 in the alphabetical order. If the data are discontinued due to a track shift or the like on the way of data writing in the alphabetical order, a flag generating circuit 3 detects the interruption of data on the basis of a tracking signal indicating the track shift and writes a flag indicating the data error of a frame in a position corresponding to a pair of data arrayed alphabetically in the memory circuit. Thus, the mixing phenomenon of data obtained before and after the interruption which is generated by interleaving at the reproducing of the interrupted part of data can be prevented and the remarkable deterioration of reproduced sound can be improved.
